Data bars in table

[#1]

Hi,

is it possible to add data bars in JMP data table, in a similar fashion as in Excel? The closest I can come to is Color Gradient properties in Columns, but data bars would be preferred.

[#2]

Easiest would be to use Tabulate

or Table Box() with Col Plot Box()

[#3 · Accepted solution]

You could also try to play around with different display boxes and then use << get picture. For example for Big Class JMP Table using following as your formula (Expression data type)

Eval(
	Eval Expr(
		Graph Box(
			Frame Size(Col Max(:weight) * 10, 300),
			Y Scale(0, 100),
			X Scale(0, Expr(Col Max(:weight))),
			Fill Color("Red");
			Rect(0, 100, Expr(:weight), 0, 1);
			Text Color("Black");
			Text Size(200);
			Text(Center Justified, {Expr(:weight / 2), 20}, Expr(Char(:weight)));
		)
	)
) << get picture

You will end up with something like

wow!

hard to find: suppressaxes
what is doubleBuffer?

[#6]

Also, if you do not need the text inside bars, you could use Spacer Boxes instead of Graph Box. Below is quick and very hacky example (I will write better version when I have slightly more time to think about this)

Names Default To Here(1); 

dt = Open("$SAMPLE_DATA/Big Class.jmp");

dt << New Column("R", Expression, None, Formula(
	As Constant(
		left_color = "Red";
		right_color = "Green";
		minval = Col Min(:Weight);
		maxval = Col Max(:Weight);
		
		scaling = (maxval - minval) / 300;
		
		If(minval >= 0,
			minval = 0;
		);
		If(maxval <= 0,
			maxval = 0
		);
	);
	
	If(:Weight >= 0,
		right = :Weight;
		right_filler = maxval - :Weight;
		left_filler = Abs(minval);
		left = 0;
	,
		left = Abs(:Weight);
		left_filler = Abs(minval) - left;
		right_filler = maxval;
		right = 0;
	);
	
	H List Box(align("Center"),
		Spacer Box(Size(1, 20), Color("Black")),
		Spacer Box(Size(left_filler * scaling, 20), Color("White")),
		Spacer Box(size(left * scaling, 20), color(left_color)),
		Spacer Box(Size(1, 20), Color("Black")),
		Spacer Box(size(right * scaling, 20), color(right_color)),
		Spacer Box(Size(right_filler * scaling, 20), Color("White")),
		Spacer Box(Size(1, 20), Color("Black"))
	);
));

With negative values:

Also, if you would like to have feature like this in JMP, create post to JMP Wish List. 

[#7]

wow, many orders of magnitude faster!

I would have edited my earlier post, but this new community layout has made user experience worse than it was before... so I will create new message (I would have liked to add spoiler tags to the JSL)
